Teflon® is one of the most used polymers
Teflon® is one of the most commonly used polymers, along with polyethylene, polypropylene, nylon and polyurethane. Each polymer has a well defined purpose. When a polymer breaks, it is recycled or just thrown away. Imagine if you could easily repair that polymer break. Imagine if you could easily combine a polymer, such as Teflon®, with aluminum, or with silicone rubber, or even with wood. Purposes of polymers are expanded. The utility of every polymer is increased. News flash. Our patented Polymer Bonding Process (Process) will bond Teflon® PTFE, any polymer, to itself, to ANY other poly and/or to any other substrate. We must give our usual disclaimer. The Process will not permanently bond glass, stainless or alloy steels.
Whenever and wherever we say that we can bond Teflon® PTFE, the reaction, of course, is skepticism. We understand your disbelief. Skepticism is the reason why we have a 100% customer satisfaction money-back guarantee. If any of our products or kits do not meet your performance expectations, we will refund your purchase price. Simply return the item. So far, after having sold thousands of kits, we have only made one refund. Find out why on the ‘Don’t Glue Polypropylene, Bond Polypropylene’ page. The reason we make sure in particular to highlight our guarantee for Teflon is that it is a fluoropolymer. This fact is another cause for initial disbelief, as fluoropolymers are hard to bond.
They are difficult to bond because they have very stable chemical bonds that are short, strong and inert. These strong, stable, bonds are also why Teflon is slippery to the touch. This same slipperiness is why a ‘glue‘ will not do the job. Glues work on a superficial level and this fluoropolymer is too slick for it to and form a glue join. Molecular bonding works on a deeper level by breaking through the bonds and interlacing with them, through the formation of covalent bonds. These covalent bonds are permanent and will not degrade over time. There is one more pertinent fact about Teflon® that you must know and it is covered at at the bottom of the page.
Our most informative video
We developed the Process in 2016 and started researching. We are still researching. At this point our Teflon® offers the most complete video we have on the Process. The video below should answer all your questions on the Process and on how to bond Teflon®, though there is still the critical fact at the bottom of the page.
The Poly Kit
To execute the Process, one of our Poly Kits is needed. Those kits include:
- a polymer-enhanced, Surface Insensitive Structural Cyanoacrylate
- our standard Activator/Accelerator (AA)
- the Poly Prep, an adhesive promoter for polymers and polyolefins
- easy to follow step-by-step instructions
The steps for bonding Teflon to itself or to a poly surface.
- Use sandpaper or steel wool to rough the Teflon or PTFE surface.
- Clean the surfaces with a cleaner that will not leave a residue.
- Wipe with a soft cloth.
- Saturate the Teflon and the poly surface with our Poly Prep, an adhesion promoter for polymers.
- Spray one of the poly surfaces with our Activator/Accelerator (AA).
- Warm both the Teflon and poly surfaces with a hair dryer or heat gun. By touch, you want the silicone/poly just to below hot. By temperature, about 120 degrees F.
- Apply an SI Structural Adhesive to the opposite surface from where you sprayed the AA. Make sure that the SI adhesive reaches the edges of the join.
- Very firmly Firmly press the two surfaces together for at least 15 seconds.
- Apply a bead of the SI Structural Adhesive to the seam between the surfaces.
- Spray the seam with the Activator/Accelerator.
As a result of this process, the two Teflon surfaces will be bonded. Operational strength is achieved almost immediately, but the strength of the bond is directly proportional to the amount of time it is given to fully cure.
To bond Teflon to steel; to bond Teflon to aluminum; to bond Teflon to metal
- Rough the surface of Teflon with sandpaper or steel wool.
- Sand the steel, aluminum or metal first with a coarse grade of sand paper.
- Then sand the steel, aluminum or and the metal with a low-grit (400 or 600) coarse sand paper. You want a near white finish or steel or polished surface for aluminum and other metals. It makes a difference.
- Clean all surfaces with a cleaner that will not leave a residue.
- Wipe with a clean soft cloth.
- Saturate the Teflon surface with our Poly Prep, an adhesion promoter for polymers.
- Spray a solvent based Activator/Accelerator (AA) on either the Teflon or metal.
- Warm the Teflon surface with a hair dryer or heat gun. By touch, you want the silicone/poly just to below hot. By temperature, about 120 degrees F.
- Apply an SI Structural Adhesive to the opposite surface from where the AA was sprayed.
- Firmly press the two surfaces together for a minimum of fifteen seconds.
As a result of this process, the Teflon and metal surfaces are bonded. Operational strength is achieved almost immediately, but the strength of the bond is directly proportional to the amount of time it is given to fully cure.
The Polymer Bonding Process
A step-by-step guide to use the Process to bond Teflon® appears below.
- Rough the Teflon® surfaces with a medium to fine grit of sand paper.
- Clean the surface with any cleaner that will not leave a residue.
- Wife with a clean cloth.
- Saturate the Teflon® surfaces with the Poly Prep. Non poly surfaces do not need to be primed, but they do need to be roughed, then cleaned. Metal surfaces need to be prepped to a near white or polished state. Let the Poly Prep dry.
If you do NOT need work time. If you need work time drop down to number 9.
- Spray one of the Teflon® surfaces with the Activator/Accelerator (AA). Let the AA dry.
- Warm the Teflon® surfaces.
- By touch, just below hot.
- By temperature, about 120 degrees F.
- Apply the SI Structural Adhesive to the opposite surface from where you sprayed the AA.
- Use continuous circles to apply the SI adhesive.
- Make sure the adhesive reaches to the edges.
- Align the surface and firmly press together for 10-15 seconds. Let cure for an hour.
If you need work time
- Warm the Teflon® surfaces .
- By touch, just below hot.
- By temperature, about 120 degrees F.
- Apply the SI Structural Adhesive to one Teflon® surface.
- Use continuous circle to apply the SI adhesive making sure the adhesive line is unbroken.
- Make sure that the SI adhesive reaches the edges.
- Align and press the pieces together for 6-8 seconds.
- Spray the seam with the AA. Let cure for an hour.
With Teflon®, your result, every time, will be hard to believe. We have used Teflon® as the base for demo pieces since the beginning. There was only one time where we had problems. Once, when we ordered more Teflon® for testing, we did not realize that there was two types of Teflon®, virgin Teflon® and manufactured Teflon®. Unknowingly, one time we ordered manufactured Teflon®. Suffice it to say that the bonds did not hold. The manufactured Teflon® delaminated. Pass on the knowledge. Our advice? Always order virgin Teflon®.
Save 15% With Tech-Bond Kits
Any of our Poly, Deluxe or Professioanl Kits will bond Teflon to itself and any other substrate; except stainless steel and glass.

I didn't even realize that what I was trying to repair was teflon. I was trying to fix my deck. I thought it was wood. Of course, it didn't occur to me until MANY failed attempts to glue the 'wood' together, that I remembered putting waterproof sealant on it. I looked it up and it had teflon in it. I coated my whole deck in teflon! Luckily, the section I needed to fix was relatively small. I primed it first with the prep, followed the instructions and it finally worked. I probably shouldn't have put so much sealant on, but it worked out in the end.
